i can only wish i lived in an area where i could even (somewhat" pattern a fox/coyote. the area i live is probably the flattest place on earth with very limited cover. been a fox hunter for 30 years. i've seen fox laying out in the WIDE open with nary a piece of grass to hide them at -35 degree's. if the fields are drifted, they will usually always lay on the side outta the wind. but if the wind is calm, i've seen them lay right on top of a drift even when real cold out. i like north wind,and cloudy days best. bright sun throws shadows over a drifted snow field making them a bit harder to spot.
